A home extension in Malabar costs $150,000–$600,000+. Rear extension from $150K, second-storey addition from $300K. Buildana manages design, Randwick City Council approvals, and construction under one fixed-price contract.
Extending Homes in Malabar
A home extension in Malabar is often a play for the coast. This small suburb between Maroubra and Little Bay runs Federation cottages and inter-war homes on 400 to 700m² blocks, many with a rise toward Malabar Headland where a carefully set-back first floor claims an ocean or bay view. In a $2M to $3.8M market, that view level is the most valuable room you can add.
The setting comes with rules. Heritage Conservation Areas cover several streets, so those frontages get examined while rear and set-back upper work moves more freely. The ground is sandstone-dominant with substantial cliff fall on the headland, so excavation is a test-dig matter, and salt-grade fixings and coatings are standard this close to the water.
What I would check first on your Malabar block: the heritage overlay, whether a set-back level would claim a view, and the sandstone in the dig. Those decide the design.
We build these fixed-price, licence HBL 487805C. Scope the view from your roofline with us before deciding.
Buildana manages the complete home extension process in Malabar — from design consultation and structural engineering through to DA or CDC approval, and fixed-price construction to handover. Extend your home without the stress.

In a $2M to $3.8M market, no ground-floor room comes close to that view level in value.

How It Works
From First Call to Final Key
Everything that has to be right before we touch the ground. Free consultation at your Malabar home. We inspect the existing structure, check Randwick City Council's controls, measure available space, and discuss what you need. You get a clear scope, budget range, and timeline before committing. Two design moves are usually on the table: match the existing house so the extension reads as original, or contrast with it so the new section is clearly modern. Both work — choice is aesthetic, and we'll show 3D renders of both before you commit.
⏱The Malabar construction phase. Fixed price, programmed, supervised. CDC (10–15 business days) or DA through Randwick City Council depending on scope. Structural engineering, BASIX, and all documentation prepared and lodged. Construction Certificate obtained. Construction phase connects new to existing — footings, frame, roof tie-in, waterproofing at junction, internal fit-out and external finish. Staged works minimise disruption to your daily routine in Malabar.
⏱The job isn't done when the site's clean; it's done when you have keys, certificates and warranties. Final inspection focuses on the integration: paint blend, flooring transitions, ceiling height, junction waterproofing, sound transmission. The extension shouldn't feel bolted on — it should feel like the house was always meant to be this size.
